Helium-3 (3He) is an isotope of helium that has two protons and one neutron in its nucleus. It is a rare isotope of helium, 0.000134%, most of which occurs with a pair or prot…ons and a pair of neutrons in its nucleus (helium-4). When we talk about an isotope of a given element by stating the element and then assigning a number, the number represents the number of nucleons in that isotop. The term nucleon refers to one of the particles that makes up an atomic nucleus, which is either a proton or a neutron. (MORE)

In the expression: 4³ = 64, the 3 is called the exponent or the power. You would read this as "four to the power of three" or "four cubed". But if it meant 34 = 81, which is… read '3 to the 4th power' or '4th power of 3', then the 3 is called the base. (MORE)

In Ice Hockey

A team can be forced to play with as few as 3 skaters (not including the goalie) if two players take penalties that overlap. If a third player takes a penalty he waits in the …penalty box until one penalty expires to begin serving his time, thus a team never has fewer than 3 skaters on the ice. If two teams are in that situation, they would play 3 on 3. (MORE)

An electron microscope requires that the subject be dead to function. In order to receive a picture, the specimen must be coated in chemicals and put into a vacuum, a process …which will kill any living specimen. A light microscope, although not as detailed, will allow the scientist to observe living specimens. (MORE)

20c + 5 = 5c + 65 Divide through by 5: 4c + 1 = c + 13 Subtract c from both sides: 3c + 1 = 13 Subtract 1 from both sides: 3c = 12 Divide both sides by 3: c = 4 20c + 5 = 5c …+65 20c - 5c= 65 - 5.
15c = 60.
15c/15 = 60/15.
c = 4 (alternative method). (MORE)

The question has a simple answer only if the polynomial has rational coefficients. However, the question does not state that it has rational coefficients so it is not valid to… assume that is the case. So, suppose the third root is p. Then the polynomial is (x + 3)*(x - 3 + 2i)*(x - p) = (x 2 + 2xi - 9 + 6i)*(x - p) = x 3 + (2i - p)x 2 - (2pi - 6i + 9)x + (9p + 6pi) (MORE)

Tough to tell. If the missing signs are pluses, that's 3 + 3x3 - 3 + 3 With no brackets, multiplication first, addition/subtraction second. 3 + 9 = 12 12 - 3 = 9 9 + 3… = 12 (MORE)
